The CWC categorizes chemicals into three schedules based on their potential for weaponization:
Schedule 1: Chemicals that have few uses outside of chemical weapons, such as sarin and VX. Schedule 2: Chemicals that have legitimate small-scale applications but can still be used to produce chemical weapons, such as thiodiglycol. Schedule 3: Chemicals that have large-scale industrial uses but can also be used in the production of chemical weapons, such as phosgene.
